    摘要: Silicon nitride films are formed by controlling the internal stress more precisely than conventional methods without varying its optical properties, mechanical strength, composition and density. The film is formed by sputtering, using an inert gas or a mixture of an inert gas and nitrogen, onto a substrate while keeping the substrate temperature within a given temperature range according to the pressure of the sputtering gas or gas mixture, the two being interrelated, thus carefully and precisely controlling the internal stress of the film formed.
